Please remember: that several people worked VERY VERY hard
to make FreeBSD performant.  It would be very difficult to
recover the performance after many cascaded performance losses.

Throwing away performance is almost an irrevocable decision, and
features (once added) are difficult to remove or substantially
rearchitect (for performance.)  (Once a slow, but workable
functionality is added, the cost to recover lost performance
after the fact is very very high.)
